This paper first introduced the development of a urban earthquake disaster management information system (UEDMIS), including the system framework, earthquake and infrastructure related database, disaster estimation and decision optimization models, functions of the software and sample interface of the software. Other than the earthquake disaster information management, the UEDMIS also can be used for emergency response for earthquake and other similar disaster incidents. How can the UEDMIS be used for incidents response? This paper gives some advices and envisages secondly. © 2010 IEEE.

With the development of high-resolution satellite technology, lots of remote sensing data were applied to disaster assessment and relief. Based on the study on prioritizing search and rescue target using remote sensing image recognition, this paper described a way of how to select collapsed buildings from an earthquake affected area for search and rescue based on high-resolution remote sensing data analysis, including the rules and analysis flow. An example was given with the data acquried during the 2008 Wenchuan earthquake to discuss the analysis models detailedly.

Earthquake is a devastating sudden onset of natural disasters. After destructive earthquakes occurrence, all levels of government and the department must quickly respond to such emergencies. Emergency drills training can improve personnel emergency management and scientific decision - making ability. This paper makes use of virtual reality simulation technology to build earthquake disaster management simulator. High - fidelity simulation of the earthquake disaster situation based on vertual earthquake emergency drilling platform enhances field feeling of trainer, improves rapid response ability of earthquake emergency management personnel.

Obtaining an accurate map of severely damaged areas immediately after an earthquake is a high priority in China. Previous methods of mapping these areas in the country have been too slow. The increasing number of mobile phone base stations provides a new means of identifying areas severely damaged by earthquakes in a very short time. In this study, we derive a new method based on the data of faulty mobile phone base stations. Our results show that areas of extreme earthquake damage identified according to base stations damaged by the Ludian and Lushan earthquakes were in very good agreement with large-magnitude seismic intensity zones outlined by the China Earthquake Administration. This indicates the reliability of our method, which can be used to help the government provide timely rescue after an earthquake and direct resources to high-priority areas. © 2016, Springer-Verlag Berlin Heidelberg.

The Tangshan area lies in the North China plain where an Ms 7.8 earthquake occurred in 1976, which is associated with a hidden active fault. To reveal the recurrence characteristics of major quakes in this area over a relatively long time, we have conducted a comprehensive study using geological investigations, shallow seismic exploration, boreholes, trench observations and geological dating. Five paleoearthquakes were recognized in a 6.4m-deep trench west to the Tangshan Asylum. Among them, the former three events occurred between 56.78 ± 4.83ka and 89.39 ± 7.60 ka, and the fourth event occurred around 6.9 ka, respectively, and then followed by the fifth in 1976. Seven boreholes were deployed crossing the ground fissure formed by the 1976 Tangshan earthquake at the site of No. 10 Middle School, where we have identified 25 liquefaction events in the boreholes TZC6-5 and 6-7. By the comprehensive analysis ofthe trench, the liquefaction events from the boreholes and the depth-time curves of drill cores, we suggest a new recurrence model of major quakes in this area. It is not a constant recurring cycle since 210 ka, instead consisting of six alternating seismically quiet and active stages. Of them, stage I (>177 ka) was a quiescent period in seismicity, stage II (from 143 ka to 177 ka) was an active one, stage III (from 102 ka to 143 ka) was quiescent again, stage IV (from 56 ka to 102 ka) had many quakes, stage V (from 6.9 ka to 56 ka) became quiet, and stage VI (from 6.9 ka to now) was the beginning of a new seismically active period.
